As already stated, it is to be noted that the construction of the side members and end members is identical with the exception that the overall lengths of the members are dierent, although this is of no material importance in view of the fact that they may be made up of plates of different lengths. Due to the position of the extensions 14 and 15, the plates may be assembled in interengaging relation, as shown in Figs. 2 and 3, in which event the lugs 15 at one end of the side member will be disposed directly beneath the lugs 14 of the adjacent member which prevents any appreciable amount of relative vertical movement between the members. At the same time the surfaces of the offset portions 19 will engage similar portions upon the adjacent plates.

When the side members 11 and end members 12 are assembled in the position shown in Fig. 1, a preferably continuous rod or bar 21 maintains the same against accidental displacement, the portions of the rod extending between the spaced lugs 18 and engaging the ribs 1'? to provide a fulcrum to permit slight oscillation of the side and end members about the axis of the rod 2l. This flexibility permits the jacket to be employed with molds having either tapered or straight outer sides and in fact permits the use with practically all types of vmolds for which the present type of jacket is intended.

In assembling the jacket, each member is placed Within the continuous rod 21 separately, but successively with the pair of lugs 18 upon the opposite sides of the adjacent portion of the rod 21 and, due to the construction of the side and end members, it will be found that they t together very readily. However, when once assembled they are maintained in assembled relation without any probability of accidental displacement. With the portions of the rod 21 bearing against the ribs 17 upon the side and end members, any tendency of the side and end members to ex during the pouring of the molten metal into the mold is counteracted and, therefore, the mold held in its most favorable condition for the pouring operation. The weight of the rod 21 is sufficient to force the side and end members into relatively tight engagement with the mold by downward movement of the rod into cooperative engagement with the ribs 17. However, the side and end members may be moved into rigid engagement with the mold by the operator positively depressing the rod 21 into engagement with the ribs 17.

If desired, the inner surfaces of the side and end members may be provided with vertically extending ribs 22, as clearly shown in Figs. 5 and 6, which is some times required, or any other configuration may be placed upon the inner surface depending upon the purpose for which the jacket is to be employed. In Fig. 4 the jacket 10 is illustrated in its position upon a mold 23 having tapered sides and rests upon any suitable support 24.

It will be at once apparent that by constructing the jacket in the manner heretofore described, replacement of either the side or end members may be readily made if for any reason one of the members becomes damaged or otherwise unusable, Whereas with the present types of jackets if a portion becomes marred or unfit for use it destroys the utility of the entire jacket. In Fig. 3 the dotted lines indicate the position to which the side and end members are adapted to move about the rod 21 as a fulcrum to adapt the different tapered surfaces. An additional advantage in having the jacket flexible and sectional resides in the fact that a greater and more equal pressure upon the mold may be exerted, due to irregularities in the latter, than with the unitary mold jackets which are at present available. A further advantage in the present construction resides in the cheapness with which the jacket can be manufactured due to the fact that a single die may be employed for forming-the side and end members, the same being interchangeable.

While I have described the preferred embodiments of the invention it is to be understood that I am not to be limited thereto inasmuch as changes and modications may be resorted to without departing from the spirit of the invention as defined in the appended claims.
